UV-Vis spectroscopy is a method in which the absorption, mainly by organic molecules, of visible (380 - 790 nm) and UV (100 - 390 nm) light is measured. In the UV-Vis range bonding electrons of molecules can be excited to cause transitions between different electronic energy levels. The transition process absorbs light at specific wavelengths and together with rotational and vibrational... Read more...More Product Announcements from Heraeus Noblelight LLC – Optics + Analytics
